The picture of the Bianchi I model via gauge fixing in Loop Quantum Gravity
Francesco Cianfrani, Andrea Marchini, Giovanni Montani
The implications of the SU(2) gauge fixing associated with the choice of invariant triads in Loop Quantum Cosmology are discussed for a Bianchi I model. In particular, via the anal…
Solution of the noncanonicity puzzle in General Relativity: a new Hamiltonian formulation
F. Cianfrani, M. Lulli, G. Montani
We study the transformation leading from Arnowitt, Deser, Misner (ADM) Hamiltonian formulation of General Relativity (GR) to the metric Hamiltonian formulation derived from th…
Gravity in presence of fermions as a SU(2) gauge theory
F. Cianfrani, G. Montani
The Hamiltonian formulation of the Holst action in presence of a massless fermion field with a non-minimal Lagrangian is performed without any restriction on the local Lorentz fram…
Matter in Loop Quantum Gravity without time gauge: a non-minimally coupled scalar field
F. Cianfrani, G. Montani
We analyze the phase space of gravity non-minimally coupled to a scalar field in a generic local Lorentz frame. We reduce the set of constraints to a first-class one by fixing a sp…
The Electro-Weak model as low-energy sector of 8-dimensional General Relativity
Francesco Cianfrani, Giovanni Montani
In a Kaluza-Klein background , we provide a way to reproduce, by the dimensional reduction, a 4-spinor with a SU(2) gauge coupling. Since additional gauge violating…
